Any way to use fly.io without credit card

Is there any way to use fly.io without a credit card. I see the buy credits options but that also needs a credit card which I don’t have. It’s not as widely used in my country. Getting a credit card with it’s related bank fee only for using fly.io is not a good usecase I’d like to know if there is any other way I can still use fly.io. This is a bit limiting unfortunately
